JOHN LAZOWSKI, OF NEWARK, NEW JERSEY.

SHIP-PROTECTOR.

Application 111m January 29,1918. Serial No. 214,267.

To all whom it may concern Bevit known that I, JOHN Lazowsxr, a citizen of Poland, resident of Newark, county of Essex, and'State of New Jersey, have invented certain new and useful Improvements in Ship-Protectors, of which the following is a specification.

This invention relates to improvements in torpedo fenders or baffle plates and part1cularly to types adapted to be secured to the sides of a seagoin vessel.

The principal 0 ject of the invention 1s to provide a fender adapted to sheer off an approaching projectile, diverting the same either above or below the vulnerable part of the ship, thereby protecting the same against danger. e

A further object is, to provide a device which may be readil applied and which presents a cushion li e surface to rece1ve the impact of a projectile and WhlCh Wlll automatically reset itself for further or,

continued operation.

These and other like objects are attained view showing the preferred form of the invention. r

Fig. 3 is a perspective view, showing a portion of the exterior hullof the vessel to which the invention is applied.

4 is a fragmental vertical transverse sectional view showing the application of the same.

Fig. 5 is a fragmental side elevational view looking from the interior of the vessel.

Fi 6 is a further enlarged sectional view showing the plunger as passing through the hull of the ship. 6 7

Throughout the several views the ship 10, is indicated to be of a conventional type-of construction, and has attached to the outer surface of the hull, at a point somewhat above the waterline a plurality of brackets 14, the same extending at spaced intervals entirely around the hull, as do similarly formed brackets 15. below and in register 7 with the upper brackets.

Hingedly secured in both the upper and Specification of Letters Patent.

' Patented Oct. 8, 1918.

lower .rows of brackets are leaf plates 16.

and 17, respectively upper and lower, the upper plates resting upon the inturned curved edges 19, of the lower plate. Both series of plates ma be either left plain, as shown in Fig. 3, b a plurality of seats adapted to contain spherical elements or balls 20, forming contact elements adapted to divert the impact of projectiles or the like which may strike thereupon, the balls rotating in their seats which, in addition to the angularity of the disposed dplates, causes the projectile to sheer away an fail to make-contact with the hull of the vessel.

ut are preferably with Secured upon the inner sides of both upper and lower plates are brackets respectively 26 and 27 in which are pivotally engaged rods 28 and 29, the same passing through the hull of the vessel, the openings being provided with stufiing boxes 30, having a anged exterior and held in" position by means of bolts 31, which pass-through the flanged elements 32, of thestufiing boxes in which are elongated elliptical holes 33,

and pliable packing or stufiing material 35', thereby permitting the rods' to move at a slight angle without admitting water to the 7 interior of the ship.

Arrangedinteriorly of the hull are rectangularcasings 37, supported by braces 38,

and securely clamped to the interior of the hull, the inner element 39, having slotted openings 40, for the inner ends of the plunger rods 28 and 29 which are pressed nor- 1n the plates extended at an angle. 'Itwil be seen that each brace 38 consists 'mally outward by means of coiled springs of, a long fiat portion having an angular foot secured to said ship side, and that it terminates in an angular portion one side of which engages the end of the casing and the other side of which engages the side of the casin so as to provide reinforcing means for rigidly holding the casing againstheadlong displacement should the fenders be struck by a torpedo. These portions arenot designated as an inspection of Fig. 2 will readily disclose the same.

From the foregoing it will be obvious that should a projectile or the like impinge upon the outer surfaces of the plates the projectile will be caused torise or lower, due

'totheangularity of the plate, and that the plate will be moved inward, due to the blow,

- Having thus described my invention what I claimas new and desire to secure by Letters Patent, is :v

1. In a device as described, in combination, a ship side, a rectangular casing secured to saidship side, upon its inner face, a series of brace members each consisting of a long fiatportion having an angular foot secured to said ship. side, and terminating inan angle portion one side of which engages the side of said casing, and the other side of which engages th eend of the casing, ,a pair of fender plates, springs in said caslng, and

rods :secured'to said fender plates and pas'sing through the ship side and carrying shoulders adapted to compressibly engage said springs.

2. Ina devlce as described, in combina- -tion,. a-ship side, formed with an opening,

flange and formed'with an opening there- I through, one of said openings having an inclined'lateral extension, a casing secured to the inner face of said ship side, the back wall of saidcasing being formed with an elon gated opening, a rod pivoted to the inner side of said fender plate and passing through v the openings in said ca s, and into the elonated opening of sa1 casing, a flange ormed upon said rod workingin said casing, a coiled spring wound upon said rod and engaging the back wall of said casing, and a packing snugly fittingin the annular bore of the cap and-engaged by thei conical' portion of the other cap. In testimony whereof I have affixed my signature.

JOHN ,LAZOWSKI.
